Fundamentals of FK Programming Programming
1
FK = Freie Kontur (German for Free Contour)
When is FK necessary? It is necessary if the workpiece drawing is not dimensioned for NC, and therefore cannot be programmed with the gray path-function pat h-function keys. However, the geometric values given in the drawing must be complete! Possible information for FK programming: Known coordinates located on the contour element or on its extension
Known coordinates located near the contour element
Fundamentals of FK Programming
2
Directional data that is referenced to another contour element
N18 parallel to AB
Information about the course of the contour and directional data of the contour itself
Motion in clockwise direction
AN (rise angle 45°)
The TNC derives the contour from known data and supports the dialog with the interactive programming graphics.
Requirements for FK programming
The FK programming feature can only be used to program contour elements that lie in the working plane.
The working plane is defined in the first BLK FORM block of the part program.
Enter all available data for every contour element. Even data that does not change must be entered in every block.
Any data not programmed is considered missing.
3
The TNC needs a fixed starting point from which it can calculate the contour elements: Use the gray path function keys to program a position that contains both coordinates of the working plane before programming the FK contour. Do not use any Q parameters in this block. For example: L X+20 Y+20 RL
Initiating FK dialogs
Show the soft keys for FK-dialog initiation You must consider the following:
What does my contour element look like?
How does my contour element start?
The following possibilities are available:
Soft key
Meaning Straight contour element, angular start Straight contour element, tangential start Curved contour element, angular start Curved contour element, tangential start Required for entry with polar coordinates
4
Interactive programming graphics: Setting/activating the graphics
Select the Programming and Editing mode of operation.
Select the main menu for screen layout.
Left: program, right: programming graphics
Shift the soft-key row.
Select whether automatic tracing is switched ON or OFF. Select whether the graphic should be shown with block numbers (SHOW) or without them (HIDE).

Converting FK Programs
1
Two functions are available:
Program structure (e.g. program-section repeat) is maintained; not suitable for Q-parameter programs
The control linearizes the programs and calculates the respective Q-parameter values Select the program you want to convert. Shift the soft-key rows until the CONVERT PROGRAM soft key appears. Select the soft-key row with functions for converting programs. Convert the FK blocks of the selected program. The TNC converts all FK blocks into straight-line blocks (L) and circular-arc blocks (CC, C), and the program structure is maintained, or Convert the FK blocks of the selected program. The TNC converts all FK blocks into straight-line blocks (L) and circular-arc blocks (CC, C), and the TNC linearizes the program. The name of the file created by the TNC consists of the old file name and the extension _nc. Example:
File name of the FK program: HEBEL.H
File name of the conversational dialog program converted by the control:HEBEL_nc.h
The resolution of the created conversational program is 0.1 µm. The converted program includes the comment SNR and a number after the converted NC blocks. The number indicates the block number of the FK program from which the respective conversational block was calculated.
Block end point / Cartesian

Absolute The coordinates of the path end point are based on the datum.
Example: X+20 Y+25
Incremental
The path end point is based on the last programmed position.

The incremental value is not based on the end point of the previous block, but instead on the end point of the referenced block.
The end point of contour element 8 is based on the end point of block 6. In block 8 you program: IX+17.5

IY+7.5 RY6
The soft keys for programming with reference blocks have an additional N in their icons:
